Abstract (en)

It comprises, in general, the following stages: preparation of a solvent-additive mixture which complies to the conditions: surface tension less than 25 din cm<-1>, steam pressure greater than 40 mm of Hg at 20 DEG C and solid residue below 4.5 10<-3> g/l, preparation of a 10<-10> M solution of the substance to be incorporated into the solvent - additive mixture, removal of the excess and rubbing with paper soaked in the solvent - additive mixture; using a water - ethanol mixture for the platting of <241>Am on an anodising thickness of 4 mu m in the manufacture of extensive radioactive sources. <IMAGE>
